MOVEMENT or VEHICLES.

Application filed September 28, 1925', Serial No. 59,098, and in Germany October 7-, 1924. I

This invention relates to means for moving; vehicles" more particularly railway wagons,

Sma llmotor vehicles driven by electricity 7 or petrol and attached either in front of or behind the Wagons andrun'ningon the same rails as the 'vva 'ons have latelybeen used for thiswpurpose; utthe weight o f'these motors prevents them from beinglm'oved, or only with considerable difficulty from one 'track fto another, or [fromthe 'frontto the rear end o'fthe Wagons, If th'eupper surface: of rails is flush iththe ground, v ordinary; motor-carriages or lorries {moving inlany direction independently (if the rails mite used but such installations are expensive, are seldom used and only in confined: factory yards:

Aecordlng to the. invention inexpensive driving devices are mounted temporarily or A Y permanently on the Wagons themselves and are adapted to rotate the wagon y' vheels or axles. Friction rollers may be'f used'to engage with the flanges or therolling surfaces 4 of: the heels and thereby propel the vehiclesi v a p r he device is quite, independent. of the track, easily transportable in any direction, cheap andsuitable for all Wagons It can 4 be driven by hand or by motor or by both.

Since the heels have a large and the axles small radius, it is'generally preferable to drive the Wheels on account of the greater leverage; If the wheels are loose on the Wheel, The required rotation can be imparted through ratchet. Wheels or other-gearing, by magnetic induction or more simply .by friction rollersi from one position to another. They are usually displaced by the aid of men,

axles two must bedriven; with fixed jwheels it is g enerall su'flicient' to drive only one The invention is r re ented byway accompanying drawing in I Fig 3 shows a modified construction in side elevation.

In Figs. 1 and 2 the drive is represented by fricti"on rollers as applied to a railwa Wagon. The fiang a of the "Wheel-l b has usually inc-lined sides and sinc to'obtaifn thefs'ame. friction, wedges-shaped wheels require "a much smaller pressure to be 'eppli'ed than plain wheel's, a suitably form-ed roller (3 enga es as shown in Figs. 11 ands, with tliepfiange a of the Wheel 6. Obviously, the plain surfaces of the 'wh'eel'b can beIdrive'n if the applied pressure isincrea'sedyalso several rollers can be arranged, driven together or separately, and the Wedge-shaped rollers can be made adjustable. The rollers "can be rotated by the wagon conductor 'by ofa hand crank'with or Without the nsertlon 0f intermediate 1 gearing. It is better, however, as shown iniFigs. I 'aind2,

the friction rollers 0 are'driven byafsi'ngle,

or multiple cylinder internal combusti'onengine d which maybe either non reversible or provided with reversing geai fer forward and backward running. El'eetric meters; "or other primeflmover's may also be used Also,

it necessary a hand eran'k drive canbe pro .vided as a reserve for the motor; I In the arrangement illustrated, the inotorfshaft drives {the shaft h; preferably provided 'vvi'th ball bearings,-and the roller 0 by two gear lwheels f and g. Thewheels" fand g they be omitted and the drive direct f om the motor shaft orjintermediate gearing imybe providedfl The position of the' fuel container can be arranged asre'quired. v

I The output of the motorandif 'required the direction of'rotation of the roller and the applied pressure can be controlled the .ear or Wagon conductor. As shown in Figs.

1 and 2,'the foot plate "2' for the conducter is arranged to alct as a lever; so that the "wei'sht of the motor a andsto'pe limit the s o {e of the foot plate @The'ineto e be fined,- ihstead of pivoted;

the frame Z, a gear wheel on the pin 70 being inserted between the motor 03 and the roller 0.

The motor (Z can be started without load and brought up to speed. On starting, when the resistance to the movement of the wagon (statical friction) is very great, the conductor moves further towards the right (longer lever arm and greater applied pressure). lVhen the wagon has started the friction is reduced and the conductor steps further towards the left, but so that the pressure applied is still sufiicient to prevent the roller from slipping. The wagon can only start when the conductor has stepped on the foot plate. After he has stepped off the drive ceases, and this stepping ofi' may be arranged tostop'the fueladmi'ssion or a coupling may be released. If necessary, the

conductor can cause the motor to brake the running of the wagon. The arrangement according to the invention ensures complete safety during the movement of the vehicles in railway'working, so that it is possible not only to move the wagons in railway stations or factory yards, but to drive them also on side lines or even on main lines.

A fixed foot plate may be provided for the conductor on which he stands on one foot, while with the other by shifting the weight of his body he controls the force applied to the lever z" and therewith the applied pressure. This pressure can be preliminarily adjusted or established by hand,

- doing away with any regulation during the drive. The lever arrangement can be constructed in many different ways, and the friction roller 0 can be pressed against the flange aby weights, for example part of the weight of the wagon, springs, screws, eccentrics, compressed air, magnets and the like.

In the modification shown in Fig. 3, a screw '0 is used for applying thepressure to the roller 0. r t I g y The frame Z, which may beformed as a hollow body or of thin tubes, as in cycles,

is, as shown in Figs. 1 and 2, arranged about the axle box a on the spring 0, and is held there by means of clamps g In order that the frame Z should hang vertically even after the conductor has mounted the foot plate 2', projections f7) provided on the frame engage with the axlebox guards 7". Obvlously, devices other than the frame] can be used in order to mount the motor with its accessories on the wagon.

The mountlng and dismounting of the driving device on each separate wagon always involves some amount-of work, so that it is advisable to fit only a few or perhaps only a single wagon withthe device temporarily or permanently, and to use this, 1n the same manner as a locomotive, to shift the other wagons.

It is obvious that many modifications can be made in the arrangements illustrated without departing from the scope ofthe inroller is mounted and a Weight displaceable on the other arm of said lever.
